本文实例讲述了JS实现的新闻列表自动滚动效果。分享给大家供大家参考,具体如下:
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Title</title> <style type="text/css"> #box{width:260px;height:100px;margin:0 auto;border:2px solid red;overflow: hidden} ul{padding:0;margin:0;list-style: none;overflow: hidden} ul li{height:24px;line-height: 24px;padding-left:10px;} a{text-decoration: none;color:#000;} a:hover{color:#f00} </style> </head> <body> <div id="box"> <ul id="con1" onMouseOut="Up()" onMouseOver="Stop()"> <li><a href="#" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >1,课程html</a> </li> <li><a href="#" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >2,课程css</a> </li> <li><a href="#" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >3,课程js</a> </li> <li><a href="#" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >4,课程jquery</a> </li> <li><a href="#" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >5,课程html5</a> </li> <li><a href="#" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >6,课程css3</a> </li> <li><a href="#" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >7,课程hp</a> </li> <li><a href="#" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >8,课程bpootstrap</a> </li> <li><a href="#" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >9,课程apicloud</a> </li> </ul> <ul id="con2"></ul> </div> </body> <script type="text/javascript"> var box=document.getElementById("box"); var con1=document.getElementById("con1"); var con2=document.getElementById("con2"); var s=document.getElementsByTagName("a"); var speed=50; con2.innerHTML=con1.innerHTML; function ScrollUp(){ if( box.scrollTop>=con1.scrollHeight){ box.scrollTop=0; }else box.scrollTop++; } var i=setInterval("ScrollUp()",speed); function Stop(){ clearInterval(i); } function Up(){ i=setInterval("ScrollUp()",speed); } </script> </html>
